Chaos of Combat (Ex)

Because of the chaos of combat, spellcasting or concentrating on spells within the area of a troop or within its reach requires a caster level check (DC 20 + spell level). Using skills that involve patience and concentration requires a successful DC 20 Will save.

Klaven marines are created by transmogrifying aquatic races such as locathah or merfolk. You can create similar land-based klaven troops by simply adjusting the speed of the troop and removing the Swim skill.
